We evaluated the analytical and workflow characteristics of the ARIES Clostridium difficile assay, a recently developed qPCR-based test for toxigenic C. difficile ARIES was compared to the illumigene C. difficile assay, a commonly employed, loop-mediated amplification technique with similar sample-to-result capabilities. Following illumigene analysis, 122 positive and 164 negative stool specimens were banked for subsequent ARIES testing. The analytical agreement between the platforms was high: 93.4% positive agreement (89...

Gastric cancer and colorectal cancer are two common malignant tumors in digestive tract. 1% to 3% of gastric cancer and 5% to 15% of colorectal cancer are definitely hereditary cancer caused by germline gene mutation. Hereditary gastric cancer includes hereditary diffuse gastric cancer(HDGC) and hereditary intestinal gastric cancer (HIGC). CDH1 gene mutation is the main reason to cause HDGC, so the first degree and the second degree family members of HDGC patients are recommended to receive CDH1 mutation detection, endoscopic examination every year and undergo preventive total gastrectomy...

Immunotherapies have emerged as one of the most promising approaches to treat patients with cancer. Recently, the entire medical oncology field has been revolutionized by the introduction of immune checkpoints inhibitors. Despite success in a variety of malignancies, responses typically only occur in a small percentage of patients for any given histology or treatment regimen. There are also concerns that immunotherapies are associated with immune-related toxicity as well as high costs. As such, identifying biomarkers to determine which patients are likely to derive clinical benefit from which immunotherapy and/or be susceptible to adverse side effects is a compelling clinical and social need...

Faecal microbiota transplantation (FMT) is the transferral of faeces from a healthy donor to a patient with a disease linked to disturbances in the gut microbiota. The treatment has been implemented at several hospitals in Denmark, and banks with frozen donor stool material have been established. The effect of FMT for recurrent Clostridium difficile infection is well-documented. FMT cannot be recommended for routine clinical use for inflammatory bowel disease and irritable bowel syndrome because of lack of data from clinical trials...

BACKGROUND: Studies in Sub Saharan Africa have shown that the Circulating Cathodic Antigen point-of-care-test (POC-CCA) is more accurate in the detections of S. mansoni than the microscopic Kato-Katz technique but less is known about the accuracy of this rapid test in detecting S. haematobium infections. This study was intended to evaluate the field accuracy of POC-CCA as a rapid test kit for schistosomiasis mapping in The Gambia. METHODS: This prospective study was conducted in 4 regions in the country...

BACKGROUND: Since 2013, several stool banks have been developed following publications reporting on clinical success of 'faecal microbiota transplantation' (FMT) for recurrent Clostridium difficile infections (CDI). However, protocols for donor screening, faecal suspension preparation, and transfer of the faecal suspension differ between countries and institutions. Moreover, no European consensus exists regarding the legislative aspects of the faecal suspension product. Internationally standardized recommendations about the above mentioned aspects have not yet been established...

Recurrent or refractory Clostridium difficile infection (CDI) has become an increasing problem in the past decade. Fecal microbiota transplant (FMT) is a highly efficacious treatment for recurrent CDI; however, a number of technical, logistical, and regulatory issues have hampered the development of an FMT capability at many hospitals. The development of a frozen stool bank of screened donor stool is an important step in the standardization of the procedure. This gives clinicians rapid access to thoroughly screened donor stool when needed, without the ethical and logistical problems associated with patient-selected donors...

With the incidence of inflammatory bowel disease (IBD) increasing rapidly in many Asian countries, including Hong Kong, it is important that patient characteristics are better understood. For example, are the phenotypes, behaviors, complications, and even treatment responses found in Asian patients similar to those of their Western counterparts? To formally address these questions, a properly designed local cohort study is needed. Whilst IBD is still relatively uncommon in Asia, the establishment of a local IBD registry will significantly contribute to the answering of these questions...

BACKGROUND: Increasing demand for fecal microbiota transplantation (FMT) has created a need for stool banks sourced from long-term healthy donors. Here, we describe our experience in recruiting and screening fecal donors. METHODS: Mailbox, newspaper, and online advertisements were used. Potential donors were required to satisfy a prescreen telephone conversation, pass blood and stool investigations, then undertake a screening interview including medical history, physical examination, and evaluation of donor selection criteria...

The enteric microbial population (microbiota) has a tremendous impact on our health and multiple disease states are associated with an alteration of the enteric microbial profile. It has been suggested that fecal microbial transplantation (FMT)--a transfer of fecal microbiota from a healthy donor to a sick person, may be beneficial for the treatment of certain diseases such as obesity, diabetes and inflammatory bowel diseases. Currently, this treatment has been approved in Israel, as well as in other countries, for the treatment of recurrent Clostridium difficile infection (RCDI)...
